Details

Bring the comfort of an infrared sauna into your home with the HeatWave Monticello 4-Person Hemlock Infrared Sauna. Built from Canadian hemlock and equipped with nine low-EMF carbon infrared heaters, the Monticello delivers even, soothing warmth with temperatures up to 140°F. Its spacious interior seats up to four adults, making it a strong choice for couples, families, or anyone who wants more room to stretch out and relax. 

The natural hemlock construction helps retain heat while giving the sauna a warm, premium appearance that works well in a basement, home gym, or large bathroom. A chromotherapy lighting system, integrated wireless sound system, ergonomic backrests, cup holders, towel hooks, and magazine rack turn the sauna into more of a complete at-home relaxation space rather than just a heated enclosure. 

The Monticello operates on 120V / 20A power, uses 2,370 watts, and includes a simple LED control panel for straightforward operation. Adjustable roof vents and an oxygen ionizer help manage airflow, while the bronze-tinted tempered-glass door gives the sauna a polished finished look. 

It measures 72" W x 46" D x 75" H externally, with interior dimensions of 68" W x 35" D x 68.5" H. Assembly is required, and Blue Wave lists an estimated assembly time of approximately 45 minutes.

Shipping and Delivery

The HeatWave Monticello ships via LTL freight because of its size and weight. The sauna is packaged in multiple cartons, with a total freight weight of approximately 471 lbs. 

Once your order ships, the freight carrier will typically contact you to arrange a delivery appointment. Because this is a large, heavy item, customers should plan for curbside freight delivery and have help available to move the cartons to their final location.

Please inspect the shipment carefully at delivery. If there is any visible damage to the packaging or product, note it with the carrier before accepting the shipment and contact Lems Supply promptly so we can help with the next steps.

Care and Maintenance

To keep the HeatWave Monticello looking and performing its best, wipe down the interior surfaces after use with a soft, dry or lightly damp cloth. Avoid harsh household cleaners, abrasive pads, or excessive water on the Canadian hemlock surfaces.

Keep the sauna interior dry between sessions and allow the adjustable roof vents to help release residual heat and moisture. Periodically check the vents, glass, lighting, controls, and heater areas for dust buildup and clean them gently as needed. 

For the bronze-tinted tempered-glass door, use a non-abrasive glass cleaner and soft cloth. Do not spray cleaner directly onto electrical components or controls.

The source literature does not provide a detailed manufacturer maintenance schedule, so for any service involving the heaters, electronics, wiring, or internal components, follow the owner’s manual and manufacturer guidance rather than attempting repairs yourself.
Returns, Damage & Order Issues

Because the Monticello is a large freight-shipped sauna, please inspect all cartons carefully when your order arrives. If you see visible damage, note it on the carrier’s delivery paperwork before accepting the shipment and take clear photos of the affected packaging and product.

If you discover missing parts, concealed damage, or another order issue after delivery, contact Lems Supply as soon as possible with your order number, photos, and a description of the problem so we can help coordinate the next steps with the manufacturer.

For returns that are not related to shipping damage or a product defect, eligibility, return shipping costs, restocking fees, and other conditions may apply. Please contact Lems Supply before returning any item so we can confirm the correct return process.

Frequently asked questions

What electrical outlet and circuit does the HeatWave Monticello require?

The Monticello operates on 120V power and requires a dedicated 20-amp circuit. Because it draws more power than a standard 15-amp household circuit is designed for, the installation area should have the proper outlet and circuit available before setup.
How many people can comfortably fit in the HeatWave Monticello?

The Monticello is designed to seat up to four adults. Its approximately 72-inch-wide exterior and spacious interior bench make it a good fit for couples who want extra room or households that want a larger home sauna.
What is the difference between carbon and ceramic infrared heaters?

Carbon heaters spread infrared heat across a larger surface area, which helps create more even warmth throughout the sauna. Ceramic heaters typically produce more concentrated heat from smaller heating elements. The Monticello uses nine carbon infrared heaters for broad, consistent heat coverage.
What temperature can the HeatWave Monticello reach?

The Monticello is designed to reach temperatures of up to approximately 140°F. Infrared saunas generally operate at lower air temperatures than traditional saunas because the infrared heat is designed to warm the body more directly.
How long does the HeatWave Monticello take to assemble?

Assembly is estimated at about 45 minutes under normal conditions. The sauna is designed for straightforward home installation, but having a second person available can make positioning and assembly easier.
